[ https://issues.jboss.org/browse/DROOLS-1622?page=com.atlassian.jira.plugi... ] Matteo Mortari commented on DROOLS-1622: ---------------------------------------- Some investigation results. This is about {{com.thoughtworks.xstream.io.xml.StaxReader}} method {{public String getAttribute(final String name)}}. When called with openjdk, this calls {{com.sun.org.apache.xerces.internal.impl.XMLStreamReaderImpl}} which respects the javadoc specs: {code:java} String javax.xml.stream.XMLStreamReader.getAttributeValue(String namespaceURI, String localName) Returns the normalized attribute value of the attribute with the namespace and localName If the namespaceURI is null the namespace is not checked for equality Parameters: namespaceURI the namespace of the attribute localName the local name of the attribute, cannot be null {code} while on IBM JDK it calls {{com.ibm.xml.xlxp.api.stax.XMLInputFactoryImpl$XMLStreamReaderProxy}} which in turns calls {code:java} String com.ibm.xml.xlxp.api.stax.XMLStreamReaderImpl.getAttributeValue(String s, String s2) {code} which in turn calling {code:java} /* */ public XMLString getAttributeValue(final int n, final int n2) { /* */ /* 1817 */ if (((SimpleScannerHelper)this).fIsNamespaceAware) { /* 1818 */ for (int i = 0; i < ((SimpleScannerHelper)this).fAttributeCount; ++i) { /* 1819 */ final com.ibm.xml.xlxp.scan.util.QName attributeName = this.attributeName(i); /* 1820 */ if (n2 == attributeName.localHandle && n == attributeName.nsHandle) { /* 1821 */ return this.normalizedAttributeValue(i); /* */ } /* */ } /* */ } /* */ else { /* 1826 */ for (int j = 0; j < ((SimpleScannerHelper)this).fAttributeCount; ++j) { /* */ /* 1828 */ if (n2 == this.attributeName(j).handle) { /* 1829 */ return this.normalizedAttributeValue(j); /* */ } /* */ } /* */ } /* 1833 */ return null; /* */ } {code} and we can see it *forcibly* check the namespace for the attribute corresponds, in this case null = 0, so it check the attribute namespace is null. This is not compliant with the Java JDK javadoc specs. -- This message was sent by Atlassian JIRA (v7.2.3#72005)
